Zusammenfassung:The present invention relates to a power control apparatus for a plasma water treatment, and the power control apparatus for the plasma water treatment according to one aspect of the present invention includes: a power converter for receiving a predetermined AC power, and outputting a voltage having a predetermined frequency; a high-voltage transformer for boosting the output voltage of the power converter according to a preset ratio, and outputting the boosted voltage; a plasma generator for receiving a power according to the output voltage of the high-voltage transformer to generate plasma; a sensor unit for measuring a water quality state value according to at least one of a dissolved oxygen amount, pH, a redox potential, and electrical conductivity according to the plasma generation of the plasma generator; and a controller for generating a PWM signal for controlling a pulse width of the output voltage of the power converter based on the water quality state value measured by the sensor unit. Accordingly, unnecessary power consumption is reduced. 본 발명은 플라즈마 수처리용 전원 제어 장치에 관한 것으로 본 발명의 일면에 따른 플라즈마 수처리용 전원 제어 장치는 소정의 교류전원을 입력받아 소정의 주파수를 가지는 전압을 출력하는 전력변환부, 전력변환부의 출력전압을 기설정된 비에 따라 승압하여 출력하는 고전압변압기, 고전압변압기의 출력전압에 따른 전원을 인가받아 플라즈마를 발생시키는 플라즈마발생부, 플라즈마발생부의 플라즈마 발생에 따른 용존산소량, pH, 산화환원전위 및 전기전도도 중 적어도 하나에 따른 수질 상태값를 측정하는 센서부 및 센서부에서 측정한 수질 상태값에 기초하여 전력변환부의 출력전압의 펄스폭을 제어하기 위한 PWM 신호를 생성하는 제어부를 포함한다.
